RING-HOLDING DEVICE.

Specification of Letters Patent.

Patented Apr. 13, 1915..

Application filed November 12, 1914. Serial No. 871,786.

and useful Improvements in Ring-Holding Devices, of which the followingis a specification.

My present invention pertains to tools; and it contemplates theprovision of a simple, compact and easily operated tool through themedium of which the packing rings of a piston may be conveniently heldin a contracted state during the putting of the piston in itscomplementary cylinder, with a view to facilitating such operation.

The invention in all of its details will be fully understood from thefollowing description and claims when the same are read in connectionwith the drawings, accompanying and forming part of this specification,in which:

Figure 1 is a top plan view showing my novel tool as arranged in properrelation to a piston cylinder, the view being a broken one. Fig. 2 is abroken side elevation of the same. Fig. 3 is a detail section, taken inthe plane indicated by the line 33 of Fig. 1 and showing the grooves inthe slide for receiving the end portions of the metallic strap. Fig. 4is a detail transverse section illustrative of the manner in which oneend portion of the strap is secured detachably in the slide.

Similar numerals of reference designate corresponding parts in all ofthe views of the drawings.

Among other elements my novel tool comprises a body 1, preferablyofrectangular form in cross-section, and preferably, though notnecessarily, provided at its under side with a series of beveled teeth2. 0n the rear end of the body 1 is an enlargement 3 designed to bearagainst the palm of the operators hand, and at the forward end of thebody is a flattened portion 1. In the I longitudinal center of saidflattened portion is a channel 5, designed for the longitudinal passageof the end portions 6 of the metallic strap 7 the forward ends of theside walls of said channel 5 being rounded as indicated by S with a viewto preventing unnecessary wear of the metallic strap. Pivoted on theflattened portion 4: is a keeper 9, equipped with a finger piece 10, thesaid keeper in the position shown in Fig. 1 being designed to retain thestrap portions in the channel, and being adapted to be swung to one sideof the channel so as to permit of the ready upward movement of the strapportions out of the channel Held against turning on and movablelengthwise of the body 1 is a slide 11 having lateral finger pieces 12.The said slide 11 is preferably equipped with a pawl 18, designed tocooperate with the teeth 2 and prevent casual forward movement of theslide I when the implement is in use. The pawl 13, however, is notessential to the successful use of my tool, and therefore, like theteeth 2, it may be omitted without involving departure from the scope ofmy claimed invention. In its upper side the slide 11 is provided withchannels 1% and 15 to receive the end parts of the strap 7. The end ofthe strap in channel 1 1 is permanently secured by a screw 16, Fig. 2.The end portion in the channel 15 is removable, and therefore with aview to holding said end portion against casual endwise movement, 1provide an enlargement 17 on the end portion, which enlargement isremovably seated in a socket 18 that communicates with the channel 15.It will also be noticed that the end portion of the strap that is placedin the channel 15 extends rearwardly beyond the slide 11, by virtue ofwhich said end portion may be readily lifted out of engagement with theslide.

At diametrically opposite or other suitable points on the strap 7 Iarrange, by preference, enlargements 20. These enlargements 2U servewhen the device is used in the placing of a piston in a cylinder havinga flared mouth, to prevent the strap 7 from passing into the cylinder.

Tn the practical use of my novel tool, the strap 7 is placed about oneof the packing rings 21 of a piston 22, either before or after the freeend of the strap is arranged and detachably secured in the channel 15 ofslide 11, as conditions demand. The operator then places his hand on thetool in such manner that the enlargement 3 bears against the palm of hishand while his fingers embrace the lateral projections 12 of the slide11. The operator then draws the slide 11 toward the enlargement 3 and byso doing contracts the packing ring 21, and 1n that way assures the saidring entering the plston cylinder incidental to the insertion. of thepiston.

It will be manifest from the foregoing that Without involving departurefrom the scope of my claims various changes in the form and proportionsof the parts of the ool maybe made.

Having described my invention, what I claim and desire to secure byLettersPatcm, is:

1. A tool for the purpose described, comprising a body having alongitudinally-disposed channel in its forward portion, a slide movableon saidbody in the direction of the length thereof, and a flexible straphaving longitudinally-disposed portions arranged and movable in saidchannel of the body and also having end portions connected to andmovable with the slide. 7

2. A; tool for the purpose'described, comprising a body having alongitudinal forward. channel, a slide movable lengthwise of the bodyand on the same, said slide having a channel and a socket incommunication with the channel, and a flexible strap having longitudinalportions arranged and movable in the channel of the body, and alsohaving one of its ends connected tothe slide and its other end removablyarranged in the channel'of the slide and provided with an enlargementdisposed in the socket of the slide.

3. A tool for the purpose described, comprising a body having alongitudinal channel. in its forward portion, the forward corners ofwhich channel are rounded, an enlargement on the rear portion of thebody, a keeper pivoted on the body and movable to and from a positionabove the channel, a slide movable on the body and lengthwise thereofand having lateral finger pieces, and a flexible strap having portionsdisposed in said channel, and connected at its ends with the slide.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
